Martin Logan MF20GB Motion F20 Floor Standing Speaker - Gloss Black

The ElectroMotion ESL X features a new larger XStat™ electrostatic transducer, with a radiating area over 50in2 larger than the EM-ESL model. Twin 8-inch high-excursion woofers are housed in a non-resonant asymmetrical bass reflex (ported) chamber, in a surprisingly compact enclosure. Woofers have custom engineered high-rigidity paper cones, with extended-throw driver assemblies.
